Heartwarming / My Little Caboose: Blue is Magic!

• Caboose and Church before Caboose dies:
  Caboose: Church, do you think they have cupcakes in heaven?
  Church: Yes, Caboose. They have cupcakes in heaven. And they have cookies and everything you could ever dream of.
  Caboose: Okay, good.*closes eyes* Is Pinkie okay?
  Church: Yes. Pinkie is fine thanks to you.
  Caboose: Thanks to me? Yay, I'm a hero.*laughs weakly* Do you think you can do me a favor?
  Church: Anything, Caboose. Name it.
  Caboose: Can you look after her?
  Church: Yes, Caboose. I'll look after her, I promise.
  Caboose:*Doesn't respond*
  Church: Caboose, stay with me!*Shakes him*
  Caboose: *smiles, and draws his final breath*
  • Also a Tear Jerker.
• Grif standing up to Tex to protect Fluttershy, even despite how much he gets hurt.
• Several spoilers for those not caught up, so be wary: Celestia, after learning of Caboose's revival, decides it's time for the red and blue teams to go back home since they've all obtained their cutie marks, which was what she had wanted them to do. Enter Sigma, who protests and states that Church has technically not received his cutie mark: Celestia wanted "Church" to earn his mark, but Church is actually Epsilon, and Sigma is a part of the real Church. Every fragment so far then shows up, even Omega and Gamma, stating that they too are parts of Church, and so until they all earn their cutie marks, Church has not earned his cutie mark, and therefore Celestia cannot send them back.
• The following bit, when Tucker finds a group of fake, lustful Rainbow Dashes created by Discord:
  Tucker: Come the fuck on, you can't expect me to believe you're Rainbow Dash. I mean, look at your legs. They don't look nearly as nice as hers. And her ass? Don't even get me started. Her ass is way more perfect than that. I would know since I might as well be staring at it every waking second. And probably just as many sleeping seconds too.
  Rainbow Dash: (the real one) What a pig. Why did I doubt his ability to only focus on my ass?
  Rainbow Dash: (a fake) Come on, baby. Isn't this what you wanted? To do it with me?
  Tucker: Rainbow Dash's voice sounds a lot better than that. Need to dial up the sexy a notch.
  Rainbow Dash: (the real one) See what I mean? All he seems to be interested in is s-
  Tucker: Her hair is half an inch longer than yours as well. Her eyes are a lot darker than that and you're about three shades of blue lighter than her.
  Rainbow Dash: (a fake) Aw, don't be such a party pooper when you could party in my-
  Tucker: Listen, I'm just going to stop you right there. If I'm going to do it with Rainbow Dash, I'm going to do it with the real one, not some pretenders.
  Rainbow Dash: (a fake) And if you have to wait a few years?
  Tucker: It'll probably be worth the wait.
• During Discord's challenges, Grif finds Tex stranded on thin ice, with weights around her legs, about to crash through and sink. At first he doesn't do anything about it, but a flashback of his sister in a similar situation causes him to instantly fly over, pull Tex out of the water, and start giving her CPR and mouth-to-mouth.
• One of the reasons that Twilight falls in love with Epsilon-Church is because during the Royal Wedding, he was the only one who stuck up for her.
  • Him sticking up for her, knowing how that scene went in canon, is pretty heartwarming as well.
